Apparatus for coating building wall with foam

ABSTRACT

This specification discloses an apparatus for coating walls of buildings, The forms are rigid sheets with tubes of exactly the same length as the thickness of the desired coating. Nails driven in the walls extend through these tubes. A wedge placed under the nail head holds the sheets to the walls. The foaming material is sprayed in the space between the sheet and the wall. The foam will adhere to the wall and when the sheet is removed, a smooth plasterlike will remain, or a pattern resembling wood grain, brick or any other desired finish. The foam may be sprayed on the floor and carpet or linoleum placed over it. A drop ceiling may be placed below the roof and the walls painted any color desired.

2 Claims, 5 Drawing Figures APPARATUS FOR COATING BUILDING WALL WITHFOAM STATEMENT OF INVENTION This invention relates to buildings and,more particularly, to a process of building a house and of repairing oldhouses.

OBJECTS OF THE INVENTION It is an object of the invention to provide animproved process of building a house.

Another object is to provide an improved process of building an improvedhouse that is simple in construction, economical to manufacture, andsimple and efficient to use.

Another object is to provide an improved structure and apparatus forrepairing old houses.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross sectional view of a houseaccording to the invention.

FIG. 1A is a view similar to FIG. 1 showing a window in the wall of ahouse.

FIG. 2 is an enlarged cross sectional view of a fastening means for theform and fastener.

FIG. 2 is an enlarged cross sectional view of the form for supporting onthe wall.

FIG. 4 is a top view of a wedge for attaching the form to the wall.

DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular referenceto the drawings, a house having a wall is shown. The wall may be made ofbrick, concrete, poured concrete blocks, cinder blocks or other suitablematerial, frame construction with a sheet of plywood or other materialused and the foam may be attached to the outside surface of the wall orit could be made of any other suitable material.

When the foam is placed on the inside, the outside surface ll of theblocks or plywood may be painted, or have a suitable sheet such as vinylor other plastic adhered to it or finished to the taste of the builder.

The floor 12 may be of poured concrete poured on the ground, or of anyother suitable material. A covering 13 of foam material can be placedover the floor or a sheet of plywood may be used and the entire floorcovered with carpet, linoleum or other floor covering material.

A roof may be used, made up of conventional rafters 14, covered with asheet of metal or plywood 16. A coating 15 of rigid urethane foam,one-fourth inch to 2 inches in thickness, may be sprayed over the entiretop of the roof.

The forms 17 will then be attached to the walls of the building eitherto the inside or outside. The forms 17 may be made of plywood or othersuitable sheets of rigid material. A Tedlar (Dupont trademark) material30 noted for its durability and weathering qualities may be laid overthe forms. The forms may be provided with a surface simulating astructural material like stone, like brick,or wood grain to give thefinished foam the appearance of wood, brick or stone. The forms may beof a convenient size for handling. For example, they ma be 8 feet by 4feet and three-fourths inch thick.

he forms 1 WI" be held at a specific spacing from the wall by sleeves18. Sleeves 18 may be made of pipe nipples threaded at their outer endat 20 and thus screwed into form 17. The nails 21 will be hardened sothey can be driven into concrete or masonry. Slotted wedges 22 will bedriven between the forms 17 and the heads 23 of the nails. Thus theforms 17 will be held at a specific spacing from the wall. A suitablereleaser material such as a sheet of polyethylene may be laid over theforms to prevent adhesion of the foam to the form. Tubes 24-extendthrough the plywood and may be connected to a suitable dispenser so thatthe foam material may be evenly distributed in the space between thewalls and the form. Thus the foam will adhere to the wall but will notadhere to the form. A manifold 31 is attached to the form and tubes 24extend through spaced'holes in the form to distribute the foam evenlybetween the wall and the form. A drop ceiling 26 may be supported abovethe floor to complete the construction. The wheel 30 is supported on theform 17 by support 32. The form 17 may be moved about to new locationsby tilting it to horizontal position so that the wheel 30 rests on thefloor and the form may be wheeled about the floor 13 like a wheelbarrow,the operator grasping the upper end of the form when it is in thehorizontal position. The form may then be moved to the new position andsupported as shown in FIGS. 1 and 1A.

The embodiments of the invention in which an exclusive property orprivilege is claimed are defined as follows:

l. A form for covering a wall with urethane foam material comprising arelatively rigid sheet of material,

spacers attached to said sheet and adapted to engage said wall,fasteners adapted to extend through said sheet and through said spacersand to engage said wall, means for attaching said fasteners to saidsheet whereby said sheet is supported at a specific distance from saidwall,

tubes are connected to said sheet around said openings, and means onsaid tubes to connect a source of foaming material to said tubes,

said spacers comprise threaded pipe nipples, said pipe nipplesthreadably engaging holes in said sheets,

and headed nails adapted to be driven into a wall and extend throughsaid pipe nipples,

and wedge-shaped members each having a slot adapted to receive saidnails in said slots with said heads overlying said wedges whereby saidsheets are held to said wall.

2. The form recited in claim 1 wherein said form has a wheel attached tothe inside surface whereby said form may be transported when said formis transported in a generally vertical position.
